A polymer composition comprises: a) at least one block thermoplastic elastomer comprising at least one elastomer block and at least one thermoplastic block, the elastomer block(s) predominantly comprising units derived from butadiene, the thermoplastic block(s) consisting of units derived from one or more styrene monomers, b) at least one plasticizer selected from butadiene oligomers with: b1) the molar content of 1,2-polybutadiene units in said plasticizer is within a range of from 70% to 130% of that in the elastomer block of the thermoplastic elastomer, and the molar mass of the plasticizer is greater than 1500 and less than 50 000 g/mol, or else b2) the molar content of 1,2-polybutadiene units in the plasticizer is less than 70%, or greater than 130%, of that in the elastomer block of the thermoplastic elastomer, and the molar mass of the plasticizer is greater than 4000 and less than 50 000 g/mol.
